The group behind Unrevoked, a tool that roots and unlocks a variety of supported Android devices, just released a nice New Year's present for EVO 4G and Incredible owners. Version 3.3 of Unrevoked adds support for:

Droid Incredible with SLCD screens

EVO 4Gs updated to OTA 3.70.651.1

the newest EVO 4G models with HBOOT 2.02 and 2.10

Besides compatibility updates, the new Unrevoked now uses another exploit under the hood, which is supposed to be more reliable than the previously used (and now infamous) rageagainstthecage.

It's no secret that my EVO 4G runs a custom ROM called Fresh - it is one of the best EVO ROMs, free of bloatware and full of tweaks that make it fast and efficient, while keeping stability rock solid. The developer, flipz, is very good - he's responsive to Sprint OTA updates and bug reports and usually sorts out any issues in a matter of days.

Update: This breaks root! If you're already rooted, download and flash the rooted version of the update. Thanks Steven.

If you had Swype beforehand and you install the update, you may have issues with it. If you do:

... go into the installed applications settings (not the swype settings). First you must clear the application data, then uninstall the application. Then you must shutdown the phone. Then, of course, you must turn it on again.
